Tracking Review

 - The combined FDC/CDC/Charged particle PID review is scheduled to
   take place on March 27 and 28.  We discussed the pre-briefing
   documentation that we would like to have.
 - The first item is a document on the physics motivations for the
   resolution capabilities to carry out a PWA.  We have decided that
   our approach will be to compare the resolutions for GlueX to
   those for BNL E852, which was able to put out signatures for
   exotic mesons with cross section at about 3% of the non-exotics.
   We will also study with our parametric Monte Carlo the missing
   mass and invariant mass resolutions as a function of detector
   resolutions.  In this area we also need to study the affect of
   acceptance holes on the reconstructions.  This includes (but is not
   limited to) the size of the beam hole in the FDC.  One stringent
   reaction on studying these impacts is rho production.  Finally,
   we need to compare acceptance functions for GlueX to E852.
 - Curtis discussed his plans for updating the documentation for
   the CDC and aims to complete this work within the next two weeks.
   Full details are on the 
   <a href="http://www.jlab.org/Hall-D/software/wiki/index.php/Feb._15%2C_2008_Tracking_CDC/FDC">agenda page</a> for this meeting.
 - DSC will update the FDC TDR to address quench issues, rails and support
   system, ASIC characterization and studies, and cables runs.  The
   document is due to Elke by March 14.
 - We agreed that studies of the overall tracking system (with combined
   CDC+FDC tracking) will be ready for the May detector review.  In 
   addition we plan on completing studies of the overall system
   optimization, including the length of the CDC and the number of
   packages/layers for the FDC.
 - Other documentation will be provided by Fernando for the electronics,
   David on the tracking/reconstruction work, and Alex on the FTOF/PID.
